As we recently mentioned
with regards to the newly available Mac support for the Eikon USB fingerprint scanner, hardware security peripherals on the Mac have been rather thin on the ground. But coming on the heels of the Eikon, GT Security has announced an update to their SecuriKey
USB security dongle for Mac which adds encrypted Volume support. Basically the SecuriKey software creates a virtual secure Volume protected by AES 128-bit encryption on which you keep your sensitive data. To access that Volume all you have to do is plug in the USB dongle (which they call a "token"). If you remove the dongle the Mac will reset to the login screen. It's a lot like Knox
but locked via a hardware key instead of a password.
The SecuriKey Professional Edition is $129.99; there's a software only upgrade for $50 if you should already have one of the dongles.
